Allow wslpath to keep trailing slash for directories (possibly via an option e.g. --preserve-trailing-slash or --force-trailing-slash)

[vadimkantorov]

Usecase: from a WSLv1 bash get a Windows absolute dir path, to be passed to a python script to be passed to Chrome headless via selenium.

Succinctly: wslpath -a -w . gets me what I want except that I need this path to have a trailing backslash. Unfortunately, wslpath -a -w ./" still returns the same path. It would be nice to have an option to return a trailing backslash for a directory in an easy way. My current workaround: $(wslpath -a -w .)\\. This is not too bad, just a bit inconvenient, and less clear to the reader as the backslash here may be somehow leaking through the abstraction

Also, it might be nice if wslpath -a -w directly returned path to the current directory - again, not very important.

wslpath -a -w . should already do what you want for current directory. Seems like appending a trailing slash should be pretty easy to do in the python script as well?

Python script in WSLv1 thinks it's completely in Linux land, so os.sep is forward slash, and I'd like to keep my Python script as simple+portable as possible. So keeping it at the upper level of wslpath would be good. I agree, it's a minor issue, but it would be a bit nicer if wslpath could produce trailing slash as well (probably via opt-in option is best)

Looks like this got lost in the churn, I've got a fix for this in PR.
