Subject: [PATCH] fixes gh-3370: resolve extremely long search by repeated
|
||||
apply of non-greedy RE `(?:: (?:[^\(]+|\w+\([^\)]*\))+)?` with following
|
||||
branches (it may be extremely slow up to infinite search depending on
|
||||
message); added new regression tests amend to gh-3210: fixes regression and
|
||||
matches new format in aggressive mode too
