t800[12]: work around MSys limitation
MSys works very hard to convert Unix-style paths into DOS-style ones. *Very* hard. So hard, indeed, that git blame -L/hello/,/green/ is translated into something like git blame -LC:/msysgit/hello/,C:/msysgit/green/ As seen in msys_p2w in src\msys\msys\rt\src\winsup\cygwin\path.cc, line 3204ff: case '-': // // here we check for POSIX paths as attributes to a POSIX switch. // ... seemingly absolute POSIX paths in single-letter options get expanded by msys.dll unless they contain '=' or ';'. So a quick and very dirty fix is to use '-L/;*evil/'. (Using an equal sign works only when it is before a comma, so in the above example, /=*green/ would still be converted to a DOS-style path.) The -L mangling can be done by the script, just before the parameter is passed to the executable. This version does not modify the body of the tests and is active on MinGW only.
