FMSLogo Code

Fix a typo where "height" was reported as "width". Also document the interaction between -F and -W/-H.

Remove unneeded code for setting the bitmap dimensions when "-F" is given during command-line processing. These were overwritten later, so having the code was simply misleading.

Fix bug #398; the command line processing now doesn't increment past the final NUL terminator of the command line string when the command-line ends in -E, -P, or -F. The bug is that these incremented the pointer twice, once past what it presumed would be a space, but was really the NUL terminator, then once again to get to the next command-line parameter. If the command line were a multiple of 8 characters, then the memory past the NUL would be unallocated (by probably mapped) memory which FMSLogo would attempt to interpret as a command-line. For some reason, the four bytes after the command line always began with an 'F', although looking at it in the debugger, it did not look like a string.

My fix is to stop when it reach the NUL, instead of incrementing past it. This retains the backward-compatible (and silly) behavior of ignoring any single character after these parameters.

Add sort.cpp to the set of source code that must be compiled.

Fix some incorrect information in some comments about object NODEs.

Remove a redundant setting of the an object's proc node to NIL when the memory debugging code removes the interned objects. This was probably a copy&paste error.

Create the object's mutable flags without using make_intnode(), since intnodes are supposed to be immutable and could (with a future optimization) return an existing int node for commonly used integers.

Fix a typo in a comment. Remove an unneeded #include.

Extend the build to provide line-level profiling/coverage information

Fix bug #466: flush the clipboard before exiting so that its contents remain available after FMSLogo exits.
