Re: [PATCH v3 3/3] t2400: rewrite regex to avoid unintentional PCRE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Just for reference, here is a summary, as a squashable commit, of
the message I am responding to.

---- >8 ----
Subject: [PATCH] SQUASH???

(remove this part of the message while squashing)
Use ` `, not `[ ]`, as the proposed log message described.

(append to the proposed log message of the previous)
Also, do not write `\+` in BRE and expect it to mean 1 or more;
it is a GNU extension that may not work everywhere.

Remove '.*' at the end of a pattern that is not right-anchored.
