t2025: Tell tail explicitly to read from stdin

Our current version of bash 3.1.17(5) can not parse the following snippet
correctly
p=abcd
abspath=/$p
subdir="x$(echo "$p" | tail -c $((253 - ${#abspath})))"
as it returns
tail: cannot open `253' for reading: No such file or directory

This is fixed in bash 3.1.20(4), I did not check earlier versions.

t1508: Be more clever than msys path substitution

A string of the form "@/abcd" is considered a file path
by the msys layer and therefore translated to a windows path.

Here the trick is to double the slashes.

The msys patch translation can be studied with the following
test program:

 #include <stdio.h>
 #include <stdlib.h>

 int main(int argc, char** argv)
 {
 unsigned int i;
 for(i=1; i < argc; i++)
 	printf("argv[%d]=%s\n",i, argv[i]);

 exit(0);
 }

fixup! t0061: Work around a line endings issue with newer versions of cat on MSYS

This reverts commit 57a35fd.

test_cmp_text is not defined anymore and as of 4d715ac
(Windows: a test_cmp that is agnostic to random LF <> CRLF conversions)
this workaround is also not required anymore.
