comparison util.c @ 792:724bbec47f86

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Use a new fatal_error function instead of calling fprintf and exit for fatal errors. This new function more gracefully handles the case in which BlastEm was not started from a terminal or disconnected from ther terminal (Windows).
