man2hlp: remove escaping from dashes in section titles

[zyv]

Proposed changes

Some 15 years ago, I did a mass-fixing of unescaped dashes in the manual pages, including section titles (8a692f9). Unfortunately, our man2hlp converter wasn't able to remove escaped dashes form the section titles. Now it can.

Just out of curiosity: what's the difference between - and \- in manpages?

In particular, Debian sticks to \- and regularly submits patches upstream for "offending" manual pages...

So I guess it's only imporant to use \- where it really needs to stand for the ASCII - char, e.g. \-\-version, ctrl\-alt\-right=... etc.

The \ could be omitted in plain English text, such as Options of editor in ini-file, mc - Visual shell for Unix-like systems etc.?

But it's probably easier just to be consistent and use \- throughout, rather than have to stop and think each time?

Yes, exactly, especially as distro linting tools do not differentiate between the two usages.
