Integrated: vcs: better regex for real names

[Erik Helin]

Hi all,

please review this patch that makes the real name regular expression in the commit message parser accept essentially
all characters except the one used in e-mail addresses.

Testing:
- [x] Added a new unit test
- [x] `make test` passes on Linux x64

Thanks,
Erik
