I’m used to doing the same, but some coding style guides present a
good reason to avoid doing that[1]:

    6.2: Strings that cause the line to go over 100 characters
    should not be written across multiple lines using string concatenation.

I have actually found myself trying to grep for an error message ang
failing to find it in code at first try because it was line-broken at
a non-obvious point.
