(Not) recognizing absolute path to command

[fwunderl]

Hi, first of all: Thanks for your work!
I noticed the following inconsistencies between Windows and Mac/Linux:

On Mac/Linux an absolute path to an executable file returns true
e.g. /usr/bin/ssh -> true

On Windows an absolute path is not accepted:
e.g. c:\Program Files\putty\plink.exe -> false

While this just seems to be an inconsistency, the following is certainly a bug:

On Mac/Linux all directories are recognized as "existing commands":
e.g. /usr -> true

I know this was last posted on over a year ago--No clue if you ever figured this out or not.

I have run into the same issue in a project of mine. After digging a bit into the code, it seems the error is because the commandExistsWindows() functions include a RegEx pattern to check for valid file names before testing if the command exists or not. This check will return false if the path given includes a :, which is normally not allowed in a Windows path, but is required for an absolute path, e.g. C:\Program Files\....

I found a better RegEx pattern for matching paths and will try to issue a pull request later today.
