Support running a cell from script w/ local functions.
matlab-shell.el: (gud-matlab-marker-regexp-plain-prompt): New regexp. (matlab-shell-prompt-appears-hook): New hook (used below) (gud-matlab-marker-filter): When returning output, if a prompt is included, call the matlab-shell-prompt-appears-hook. (matlab-shell-run-cell, matlab-shell-run-region-or-line): Move (matlab-shell-run-region): Extract inline code to find 'command' to new fcn. (matlab-shell-region-command): Function to extract code to run as cmd. (matlab-shell-region->commandline): Copy from run-region as new fcn. Fix up to better clean up blank lines, and excessive whitespace. (matlab-shell-extract-region-to-tmp-file): NEW. This is like region->commandline but puts content into a speicially named m file. If any functions are needed from the script, pull those along. (matlab-shell-cleanup-extracted-region): Delete files created by above. Called from the new hook.
