Less 581.2 is here, and it has a ".2" in the version string, which can't
be parsed as a usize.
Update the check to find a non-digit character rather than a space. This
ignores the minor version, but parses the major version correctly.
Do not ignore `BAT_CONFIG_PATH` if it doesn't exist. Both when
generating a new config file with `--generate-config-file` and
when attempting to read the config.
Also, provide a better error message in case the file can not
be created.

The change in `create_highlighted_versions.py` fixes a "unknown theme
"'1337'" warning. The single quotes were wrong. `bat` was always falling
back to the default theme, so let's use that for now.
Fixed by implementing the proposal by sharkdp:
* Allow PAGER=bat, but ignore the setting in bat and simply default to
less. Unless of course, BAT_PAGER or --pager is used to overwrite the
value of PAGER.
* Disallow the usage of bat within BAT_PAGER and --pager.
This will fix#614 by making it clear what is wrong by showing the
following error message:
Failed to load one or more themes from
'/Users/me/.config/bat/themes' (reason: 'Invalid syntax theme
settings')
We also need to add a check if theme_dir.exists(), otherwise an absent
dir will seem like an error:
Failed to load one or more themes from
'/Users/me/.config/bat/themes' (reason: 'IO error for
operation on /Users/me/.config/bat/themes: No such file or
directory (os error 2)')
(This is the same check we already have for syntax_dir.)
To trigger/verify the changed code, run
bat --list-languages # or -L
This is the last clippy warning in the code that you get if you run
cargo clippy --all-targets --all-features -- --allow clippy::style
so by fixing it it becomes easier to spot when a new warning is
introduced (that does not belong to the clippy category clippy::style).
And by making it easy to spot new warnings, we increase chance of such
regressions not ending up in the code base.
