[PATCH 3/3] files: avoid mistakenly setting the column number to a given line number

When the file 'foo:24' exists (but not 'foo') and the user wants to
use the colon notation to place the cursor on a certain line, then
nano would first interpret the given line number as a column number,
before noticing that 'foo' does not exist and then skipping the first
colon.  So, when such a misinterpretation occurs, the column number
needs to be reset to zero.
