Make util.find_exe alway returns existing file, fixing issue1459

It seems like the old behaviour with different handling for commands with and
without path was intended, but I think this behaviour of util.find_exe is
better:
* Always returns existing file
* or None if command not found - no default
* Windows: Returned file thus always ends with extension from PATHEXT

This fixes http://www.selenic.com/mercurial/bts/issue1459. The change might
fix other unintended behaviour too.

import os, sys
from mercurial import hg, ui

TESTDIR = os.environ["TESTDIR"]

# only makes sense to test on os which supports symlinks
if not hasattr(os, "symlink"):
    sys.exit(80) # SKIPPED_STATUS defined in run-tests.py

# this is what symlink would do on a non-symlink file system
def symlink_failure(src, dst):
    raise OSError, (1, "Operation not permitted")
os.symlink = symlink_failure

# now try cloning a repo which contains symlinks
u = ui.ui()
hg.clone(u, os.path.join(TESTDIR, 'test-no-symlinks.hg'), 'test1')
