The `--verbose` option is only used by `flake8`, itself,` when parsing
and handling preliminary options. After parsing and merging options
from the configuration file, there is no other behavioral impact to the
core of `flake8`. In other words, setting `verbose = ...` in a
configuration file doesn't change the logging verbosity.
While the `FileProcessor` does expose a `verbose` attribute, obtained
from the parsed options, the verbosity of the core of `flake8` should be
consistent with how a plugin may respond to the attribute's value.
Previously Flake8 parsed both
max-line-length = 110
And
max_line_length = 110
From the config file without issue. When we updated our logic, I forgot
to test for that and we lost that behaviour temporarily.
Closes#152
ConfigFileFinder should absolutely handle broken/invalid config files
by refusing to try to parse them. Here we catch the ParsingError,
log the exception, and then return normally. The RawConfigParser
instance is perfectly valid still and will behave as if nothing had
been read and we just need to indicate that we didn't find any files
worthy of reading.
