Revision 7e6d6f7610965906d071022615bf64f14c60c0d2 authored by Johannes Sixt on 12 June 2019, 16:33:48 UTC, committed by Junio C Hamano on 12 June 2019, 20:20:56 UTC
git-mergetool spawns an enormous amount of processes. For this reason, the test script, t7610, is exceptionally slow, in particular, on Windows. Most of the processes are invocations of git. There are also some that can be replaced with shell builtins. Avoid repeated calls of `git ls-files` and `awk`.
