Using the backslash escape character returns an error in regexprep and Octave
dev with this call:

octave> regexprep('\','\\','backslash')
error: regexprep: \ at end of pattern at position 1 of expression

while it does not return the correct answer here:

octave> regexprep('\b','\\b','backslash')
ans = \b

It is fine with Octave 3.6.2.
