Subject: gitweb: Better regexp for SHA-1 committag match
X-Git-Url: https://git.ladys.computer/Gitweb/commitdiff_plain/bb9db3a422e701cef902d1018a4ad87102f4711080b7e323995fdd9802d60884

gitweb: Better regexp for SHA-1 committag match

Make SHA-1 regexp to be turned into hyperlink (the SHA-1 committag)
to match word boundary at the beginning and the end.  This way we
reduce number of false matches, for example we now don't match
0x74a5cd01 which is hex decimal (for example memory address),
but is not SHA-1.
