2.7.2: Parentheses in tag breaks the log message

[opty77]

elogind uses parentheses in tag, e.g.:

        r = fork_agent("(polkit-agent)",

which breaks the log message:

2025-05-03T17:56:38.931881+02:00 vodopnik - - - - (polkit-[15623]: Failed to execute /usr/bin/pkttyagent: No such file or directory

Yes it does, as does systemd, so it should not be a problem.

This is here: https://github.com/elogind/elogind/blob/33f2dc1ce3e5cb0a845f27fbc276396d6614c11c/src/shared/polkit-agent.c#L50
Which is the same as in here: https://github.com/systemd/systemd/blob/00a12c234e2506f5cab683460199575f13c454db/src/shared/polkit-agent.c#L50

The error
(polkit-[15623]: Failed to execute /usr/bin/pkttyagent: No such file or directory
means that /usr/bin/pkttyagent is not there.

See elogind/elogind#312 (comment).

This is another regression after I decided to tighten up the parser. It's a relatively simple fix, although iirc from the RFC, it's a bit undefined.
