store: eliminate unneded last assignment to n in _auxencode() The check for period or space at the end of the string is the last one, the local variable n is thus not used anymore.

store: unindent most of the contents of the for loop in _auxencode() by refactoring for i, n in enumerate(res): if n: <main code block> to for i, n in enumerate(res): if not n: continue <main code block> (no functional change)

store: optimize _auxencode() by assigning to the list elements of the path

store: optimze _auxencode() a bit by grouping the reserved names by length This reduces perffncacheencode wall time on Windows 7 x64 for my netbeans clone here from 4.3 to 4.0 (7% faster).

store: explain "aux.foo" versus "foo.aux" in doc of _auxencode()

store: add 'com0' and 'lpt0' doctest cases for _auxencode() These are already covered by test-hybridencode.py, but they are so noteworthy that I think they deserve being shown right in that doctest.

record: fix display of non-ASCII names in chunk selection b013baa3898e fixed display of non-ASCII names in file-selecting prompt, but display in chunk selection remained broken. The reason is that using '%r' in string formatting results in calling `repr` on file names, thus mangling non-ASCII ones.
