I just ran across a problem when inputting files. Apparently LaTeX adds
a space after the inputted file.

For me this led to a strange larger space being added after the inputted
file which was supposed to be only the first part of a paragraph.
Maybe there could be a checkbox in the Child Document dialog that reads
something like "remove space after child" or so when the Include Type is
Input. This then automatically adds the \unskip or \endinput command.
Maybe that should even be the default?
