Which reinds me that the expression fishing for "which" is really poor.
How about something like the following:

Subject: [PATCH] Reduce false positive in check-non-portable-shell.pl
check-non-portable-shell.pl is using simple regular expressions to
find illegal shell syntax.
Improve the expressions and reduce the chance for false positves:
"sed -i" must be followed by 1..n whitespace and 1 non whitespace
"declare" must be followed by 1..n whitespace and 1 non whitespace
"echo -n" must be followed by 1..n whitespace and 1 non whitespace
"which" must be followed by 1..n whitespace, a string, "end of line"
