log: range_set_append: Assertion failed with -L:funcname:

Hi all,

I encountered the following assertion failure when running in a local
clone of the https://github.com/nodejs/node.git repository:

$ git log -L:writeFileSync:lib/fs.js -L:appendFileSync:lib/fs.js aa67b1^..aa67b1
git: line-log.c:71: range_set_append: Assertion `rs->nr == 0 || rs->ranges[rs->nr-1].end <= a' failed.
Aborted

I was able to provoke the same assertion failure in the git repository
with the following:

$ git log -L:print_one_push_status:transport.c -L:transport_summary_width:transport.c f9db0c^..f9db0c

(FWIW, f9db0c is a merge commit while aa67b1 is not.)

I was able to reproduce the error with git built from 13b8f6 (the
commit which introduced git log -L:pattern:file) as well as current
next (91ed5b).  The backtrace from next is attached.

Any assistance to avoid or fix the error would be greatly appreciated.

Thanks,
Kevin
