Sorry I didn't read your mail carefully enough.

True.

So another option is to disable all substitution of "--" and just use
the "—" character when it is explicitly needed. The documentation is
using UTF-8 after all. This would also fix the usage of "--" in the
manpages, e.g.

	You've now initialized the working directory--you may notice ...

in gittutorial(7). On my setup, with "--" replaced with "—", I get the
following nroff code:

	You've now initialized the working directory\(emyou may notice
	...
