git grep shows the same hit repeatedly for unmerged paths

gitster · gitster · commit 6326cee51b21 · 2007-12-05T16:16:40.000-08:00
When the index is unmerged, e.g. $ git ls-files -u 100644 faf413748eb6ccb15161a212156c5e348302b1b6 1 setup.c 100644 145eca5 2 setup.c 100644 cb9558c49b6027bf225ba2a6154c4d2a52bcdbe2 3 setup.c running "git grep" for work tree files repeats hits for each unmerged stage. $ git grep -n -e setup_work_tree -- '*.[ch]' setup.c:209:void setup_work_tree(void) setup.c:209:void setup_work_tree(void) setup.c:209:void setup_work_tree(void) This should fix it.
