RE: Problem with Text mounts after updating using setup.exe
Could someone confirm this is introduced in grep-2.5.1a-4, grep-2.5.1a-2 seems to be good?

I prefer not to have to add workarounds, this problem is visible in the department buildtools, a rather large set of hundreds of make scripts, luckily must users haven't upgraded yet. If someone else could confirm it would help with making a bit more formal bugreport if someone is intrested.

You won't get them on a binmode mount. Looks like grep opens the input and output in binmode. The shell redirection opens the output in the mode of the mount where the output is to be placed. Thus, grep prints out the full input string (including the CR) and the shell happily prepends another CR to the LF. A workaround would be to put the output file on a binmode mount. Another thing that *might* work is using input redirection as well as output (i.e., "grep a < test.txt > test2.txt"). FWIW, I can't reproduce this with grep-2.5.1a-2, which means this behavior was introduced in -4.
