doc: escape .hg at bol in manpages with make (issue1072)
This works around a bug in old docbook stylesheets.
Remove .*.swp example from hgignore.5.txt.
Diagnosis and workaround thanks to Alexis S. L. Carvalho.
highlight: Generate pygments style sheet dynamically
This patch allows a per-repository (for example, within a hgwebdir) selection
of pygments_style web option. No static .css files required.
