Concatenates PCX files vertically.
Each parameter, except the last, is assumed to be an existing PCX file.
All file names assume a default PCX extension, which may be overridden.
The last parameter is the output file name, and is overwritten
(without warning) if it exists. Globals allowed on input files.
The first file in the list determines the horizontal size.
If subsequent files are a different horizontal size than the first,
they are truncated or filled on the right side to match file 1.
The output file contains a vertical concatenation of all the others.
