Bug ID: 56528
Summary: "bad flags delimiter" - improve helpfulness
Product: Apache httpd-2
Version: 2.5-HEAD
Hardware: PC
OS: Linux
Status: NEW
Keywords: PatchAvailable
Severity: enhancement
Priority: P2
Component: mod_rewrite

Improve error reporting in mod_rewrite
The parser in mod_rewrite always interprets the third argument to
RewriteRule/RewriteCond as optional flags. However, unescaped whitespace is
fairly easy to accidentally insert into a RewriteRule/RewriteCond directive.
When this happens, "bad flag delimiters" is displayed since the rogue
whitespace causes the parser to interpret a chunk of one of the args as flags.
This error is a spectacularly bad way to express this (even if it's strictly
true).
The attached patch attempts to improve the error reporting of the relevant
section in mod_rewrite.
