[PATCH 1/7] autoconf: GIT_CONF_APPEND_LINE: change signature

[Stefano Lattarini <stefano.lattarini@xxxxxxxxx>]

From:

   GIT_CONF_APPEND_LINE([VAR=VAL])

to:

   GIT_CONF_APPEND_LINE([VAR], [VAL])

This is only a preparatory change in view of future refactorings.
No semantic change is intended.  In fact, the generated configure
file doesn't change at all.
