fix(git): Git commit search regex pattern improved to disable space chars in commit subject

[erayalakese]

A bug in the regex pattern was causing all commit subjects which contain colon to catch by regex. Fixed by disabling space character in type.

Before this change, this commit message was caught by regex:

'Merge branch \'master\' of github.com:erayalakese/adventure'

which shouldn't be in the change log.
