commands.

#require rust

Define an rhg function that will only run if rhg exists
  $ rhg() {
  > if [ -f "$RUNTESTDIR/../rust/target/debug/rhg" ]; then
  >   "$RUNTESTDIR/../rust/target/debug/rhg" "$@"
  > else
  >   echo "skipped: Cannot find rhg. Try to run cargo build in rust/rhg."
  >   exit 80
  > fi
  > }

  file3

Listing tracked files from subdirectory
  $ mkdir -p path/to/directory
  $ cd path/to/directory
  $ rhg files
  ../../../file1
  ../../../file2
  ../../../file3

  $ rhg files | head -n 1
  ../../../file1

Debuging data in inline index
  $ cd $TESTTMP
  $ rm -rf repository
  $ hg init repository
  $ cd repository
  $ for i in 1 2 3; do
  >   echo $i >> file$i
  >   hg add file$i
