revlog: fix typo in 'buildtext' name
There are no such things as 'deltacomputer._buildtext'. I'm not sure why this
code never ran, but we better fix the typo.
#require test-repo jshint hg10
$ . "$TESTDIR/helpers-testrepo.sh"
run jshint on all tracked files ending in .js except vendored dependencies
$ cd "`dirname "$TESTDIR"`"
$ testrepohg locate 'set:**.js' \
> 2>/dev/null \
> | xargs jshint
