replace-match - "Them" vs "Us"

[ Followups set to xemacs-beta(a)xemacs.org AND mh-e-devel(a)lists.sf.net ] This is currently being discussed on the mh-e devel list. Given the following sexp... ******************************* ******************************* GNU/Emacs returns "test passed" XEmacs returns "test failed" It obviously has something to do with the two Emacsen's implementation of 'replace-match' (doc strings of both included below). My question is: What is the best and easiest way to work around this so that XEmacs behaves the same way as GNU/Emacs? ,----[ C-h f replace-match RET (XEmacs) ] | `replace-match' is a built-in function | (replace-match REPLACEMENT &optional FIXEDCASE LITERAL STRING STRBUFFER) | | Documentation: | Replace text matched by last search with REPLACEMENT. | If second arg FIXEDCASE is non-nil, do not alter case of replacement text. | Otherwise maybe capitalize the whole text, or maybe just word initials, | based on the replaced text. | If the replaced text has only capital letters | and has at least one multiletter word, convert REPLACEMENT to all caps. | If the replaced text has at least one word starting with a capital letter, | then capitalize each word in REPLACEMENT. | | If third arg LITERAL is non-nil, insert REPLACEMENT literally. | Otherwise treat `\' as special: | `\&' in REPLACEMENT means substitute original matched text. | `\N' means substitute what matched the Nth `\(...\)'. | If Nth parens didn't match, substitute nothing. | `\\' means insert one `\'. | `\u' means upcase the next character. | `\l' means downcase the next character. | `\U' means begin upcasing all following characters. | `\L' means begin downcasing all following characters. | `\E' means terminate the effect of any `\U' or `\L'. | Case changes made with `\u', `\l', `\U', and `\L' override | all other case changes that may be made in the replaced text. | FIXEDCASE and LITERAL are optional arguments. | Leaves point at end of replacement text. | | The optional fourth argument STRING can be a string to modify. | In that case, this function creates and returns a new string | which is made by replacing the part of STRING that was matched. | When fourth argument is a string, fifth argument STRBUFFER specifies | the buffer to be used for syntax-table and case-table lookup and | defaults to the current buffer. When fourth argument is not a string, | the buffer that the match occurred in has automatically been remembered | and you do not need to specify it. | | When fourth argument is nil, STRBUFFER specifies a subexpression of | the match. It says to replace just that subexpression instead of the | whole match. This is useful only after a regular expression search or | match since only regular expressions have distinguished subexpressions. `---- ,----[ C-h f replace-match RET (GNU/Emacs) ] | replace-match is a built-in function. | (replace-match NEWTEXT &optional FIXEDCASE LITERAL STRING SUBEXP) | | Replace text matched by last search with NEWTEXT. | Leave point at the end of the replacement text. | | If second arg FIXEDCASE is non-nil, do not alter case of replacement text. | Otherwise maybe capitalize the whole text, or maybe just word initials, | based on the replaced text. | If the replaced text has only capital letters | and has at least one multiletter word, convert NEWTEXT to all caps. | Otherwise if all words are capitalized in the replaced text, | capitalize each word in NEWTEXT. | | If third arg LITERAL is non-nil, insert NEWTEXT literally. | Otherwise treat `\' as special: | `\&' in NEWTEXT means substitute original matched text. | `\N' means substitute what matched the Nth `\(...\)'. | If Nth parens didn't match, substitute nothing. | `\\' means insert one `\'. | Case conversion does not apply to these substitutions. | | FIXEDCASE and LITERAL are optional arguments. | | The optional fourth argument STRING can be a string to modify. | This is meaningful when the previous match was done against STRING, | using `string-match'. When used this way, `replace-match' | creates and returns a new string made by copying STRING and replacing | the part of STRING that was matched. | | The optional fifth argument SUBEXP specifies a subexpression; | it says to replace just that subexpression with NEWTEXT, | rather than replacing the entire matched text. | This is, in a vague sense, the inverse of using `\N' in NEWTEXT; | `\N' copies subexp N into NEWTEXT, but using N as SUBEXP puts | NEWTEXT in place of subexp N. | This is useful only after a regular expression search or match, | since only regular expressions have distinguished subexpressions. `---- -- |---<Steve Youngs>---------------<GnuPG KeyID: 10D5C9C5>---| | XEmacs - It's not just an editor. | | It's a way of life. | |------------------------------------&lt;youngs(a)xemacs.org&gt;---|
