doc: change 'revision or range' to 'revision or revset'

The phrase "revision or range" comes from a pre-revset era. Since the
documentation for ranges now is under the revset docs, and as a
helpful hint nudging users towards revsets, I think it's better to say
"revision or revset"

tests: introduce "checkeditform-n-cat.sh" script to invoke "cat" in it safely

Before this patch, a part of "test-transplant.t" fails unexpectedly on
Windows environment, because semicolon (";") in HGEDITOR isn't
recognized as the command separator by "cmd.exe".

This patch newly introduces "checkeditform-n-cat.sh" script to invoke
"cat" in it safely anywhere.

tests: use "%HG_ARGS%" in shell alias on Windows instead of "$HG_ARGS"

Before this patch, a part of "test-alias.t" fails unexpectedly on
Windows environment, because "cmd.exe" can't evaluate "$HG_ARGS"
expression in shell alias correctly.

This patch uses "%HG_ARGS%" in shell alias on Windows instead of
"$HG_ARGS" to expand it correctly.

tests: change obsolete timestamp to avoid "gmtime()" problem on Windows

Before this patch, "test-obsolete.t" fails on Windows environment,
because strings corresponded to "tm_wday" (day of the week) field are
incorrect.

On POSIX environment, "gmtime()" returns correct "tm_wday" value even
for negative "time_t" value. On the other hand, it returns incorrect
one on Windows environment. At least, "gmtime()" of the Windows
runtime library bundled with Python 2.7.3 does.

According to 9a7d0f7e0561 introducing original timestamp value '56
120', it shouldn't cause negative "time_t" value.

    test-obsolete: remove subminute timezone in test

    Obsmarker format "1" does not supports sub minute timezone. So we
    change the test to something slightly more sensible.

It replaced "-d '56 12'" by "-d '56 120'".
