tests: make chunk header of external diff glob-ed for portability
Before this patch, some tests using external "diff" command via
extdiff extension fail on Solaris, because system standard "diff" (=
/usr/bin/diff) on Solaris always generates chunk headers below:
- "@@ -1,0 +1,nnnn @@" for added file
- "@@ -1,nnnn +1,0 @@" for removed file
even though "diff" on Linux generates:
- "@@ -0,0 +1,nnnn @@" for added file
- "@@ -1,nnnn +0,0 @@" for removed file
This patch makes chunk header of external diff glob-ed for portability
of tests.
"hg diff" output follows Linux style, and there are many such diff
output lines in existing tests. This is reason why this patch doesn't
add check-code.py any rule to detect such diff output in tests.
This patch is a part of making tests using external "diff" portable,
and test-subrepo-deep-nested-change.t isn't yet portable even after
this patch.
