Hi Peter,
Not the \input command, but the end-of-line in the inputted file
is creating the space, indirectly. TeX normally appends a character
with the current value of \endlinechar to each line of an input-ed
file, and that character is later converted to a space.
Setting \endlinechar to -1 temporarily is a possibility, another
is writing a percent sign to the end of the line, yet another is
ending the written line with \relax (or a similar space-gobbling
command), and finally changing the catcode of the current
\endlinechar to 9 (ignored) also works.
Cheers, Taco
