[new check] special characters in filepaths

[jameslamb]

What should be checked?

pydistcheck should warn about the presence of filepaths with characters that can cause portability issues unrelated to encoding (#76 tracks a separate check on non-ASCII characters).

These include:

• < (less than)
• > (greater than)
• : (colon)
• " (double quote)
• / (forward slash)
• \ (backslash)
• | (vertical bar or pipe)
• ? (question mark)
• * (asterisk)

(from "reserved characters" in the Windows filesystem docs).

They also include "control characters":

• ASCII values 0-31 (docs link)
• $ (ASCII 36)

Filepaths only consisting of directory traversal characters should also result in a warning.

• /
• .
• ..
• \

Filepaths ending in the following should also result in warnings.

• .
• /
• \
• spaces (although other rules above should already prevent spaces)

What should the name of this check be?

special-characters-in-filepaths
