[PATCH v5 0/2] MR3616: cmd: added support of for loop's var names %%1, fixed expansion of outer var loop name inside inner loop
Visual Studio's native tool command prompt uses these FOR loop variables: %%1, %%2. This fix allows to use %%1 var in FOR loops.case. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=55401 -- v5: cmd: added support of for loop's rare var names (%%1), fixed expansion of outer var loop name inside inner loop cmd: added test for rare for loop vars https://gitlab.winehq.org/wine/wine/-/merge_requests/3616
From: Dmitry Sokolov <mr.dmitry.sokolov(a)gmail.com> Visual Studio's native tool command prompt uses rare for loop variables: %%1, %%2. This test covers this case.
