Console command paths cannot be specified correctly with backslashes

[Derek701]

Bitcoin Core v0.13.0 on Windows 10 (using Debug window console in GUI)

Console commands with filename arguments cause unexpected behavior when using Windows-style backslashes in paths. For example, dumpwallet D:\Bitcoin\test.txt creates D:\Bitcointest.txt. Replacing backslashes with slashes, dumpwallet D:/Bitcoin/test.txt creates D:\Bitcoin\test.txt.

The unexpected result is more confusing because dumpwallet does not print the path/filename of the created file to the console (only a blank line).

At least a note for Windows users to specify paths with slashes in the help text would be nice. Also, the help text for dumpwallet and importwallet does not indicate that the filename argument requires a full path to work correctly in the console (i.e., there's no default working directory).

The debug console has a minimal sh-like parser. You can actually use backslashes, but you need to escape them or surround with quotes (preferably single quotes, because there \ will never be interpreted as an escape sequence). E.g. either

dumpwallet d:\\Bitcoin\\test.txt
dumpwallet 'D:\Bitcoin\test.txt'

Closing in favor of #9195 which is a more general issue for tracking RPC console documentation.
