Revision 865406bc5426d5196935e37a3a5fde9c843c3e96 authored by Philip Oakley on 29 July 2019, 20:08:03 UTC, committed by Junio C Hamano on 29 July 2019, 21:51:42 UTC
Since 4b623d8 (MSVC: link in invalidcontinue.obj for better POSIX compatibility, 2014-03-29), invalidcontinue.obj is linked in the MSVC build, but it was not parsed correctly by the buildsystem. Ignore it, as it is known to Visual Studio and will be handled elsewhere. Also only substitute filenames ending with .o when generating the source .c filename, otherwise we would start to expect .cbj files to generate .obj files (which are not generated by our build)... In the future there may be source files that produce .obj files so keep the two issues (.obj files with & without source files) separate.

This test runs git rebase "interactively", retaining the branch structure by
recreating merge commits.
Initial setup:

A - C - D - E - H (master)
