config: close file even if we fail to read it
If we get an exception from cfg.read(), we would not close the file
before this patch. This patch uses a context manager to make sure we
close it.

config: catch intended exception when failing to parse config
When a new config parser was introduced in
fca54469480e (ui: introduce
new config parser, 2009-04-23), the reading side would raise a
ConfigError which was then caught in the ui code. Then, in
2123aad24d56 (error: add new ParseError for various parsing errors,
2010-06-04), a ParseError was raised instead, but the call site was
not updated. Let's start catching that ParseError. We still don't
print it in a friendly way, but that's not worse than before.

rust-hg-path: implement more readable custom Debug for HgPath{,Buf}
The default prints the vector of bytes as a list of integers. I
considered instead getting rid of the Debug trait, but we use the
Debug format in lots of derived Debug instances, so we probably do
want to implement it.
