bug#4374: find-file-at-point doesn't recognize absolute file paths with trailing line numbers. (Patch included.)

[hans bennekop]

I frequently run across absolute file paths with a trailing line-number 
  specification, e.g. ~/foo.el:7.
Find-file-at-point fails to recognize the file part and falls back to 
opening the parent dir.
Here's the (trivial) fix:
