autorevision: use sed word delimiters for better precision

Fixes wrongly replaced 'cat' in help text: $ autorevision -h usage: autorevision {-t output-type | -s symbol} [-o cache-file [-f] ] [-e name] [-U] [-V] Options include: -t output-type = specify output type -s symbol = specify symbol output -o cache-file = specify cache file lo/nix/store/1rzzq2wdn5vfgbp5y9613jpdkf8i9ag6-coreutils-8.26/bin/cation ... (Also replace all occurences per line, in case that should occur.)
