Doing this and then ...

... doing this is wrong. People can set htmldir to somewhere other than
$(prefix)/share/doc/git-doc while building and installing, but you are
not telling the munged script where it is.

Please do not contaminate the config file with something the user can
easily use a lot more standardized way (iow $PATH) to configure to his
taste.

I'd suggest dropping this bit.
