Since c7d67ab running "tig" with no options has failed with the
error "tig: No revisions match the given arguments." This was due
to a change in how the arguments for the back-end git call was
being constructed. This change caused the blank field left in
place of "(encoding_arg)" when it is empty to not overwrite
"buf" which then caused the value in "buf" to be copied into
dst_argv twice. The resulting git command failed if there was no
available revision named "log" as shown in the trace.
>From the TIG_TRACE log:
git log log --no-color --pretty=raw --parents --parents --
fatal: bad revision 'log'
This fix works by teaching tig that when it is supplied with a
blank field in the source argument buffer that it should skip
over that field and continue instead of copying the previous
field value into the destination buffer a second time.

This should apply cleanly to the tig public master whether the
mkstemps() patch I wrote has been applied or not.
