The Git CodingGuidelines prefer the $(...) construct for command
substitution instead of using the backquotes `...`.

The backquoted form is the traditional method for command
substitution, and is supported by POSIX.  However, all but the
simplest uses become complicated quickly.  In particular, embedded
command substitutions and/or the use of double quotes require
careful escaping with the backslash character.

The patch was generated by:

for _f in $(find . -name "*.sh")
do
	perl -i -pe 'BEGIN{undef $/;} s/`(.+?)`/\$(\1)/smg'  "${_f}"
done

and then carefully proof-read.

Dealing with NULs is not always safe with tr. On Solaris,
incoming NULs are silently deleted by both the System V and
UCB versions of tr. When converting to NULs, the System V
version works fine, but the UCB version silently ignores the
request to convert the character.

This patch changes all instances of tr using NULs to use
"perl -pe 'y///'" instead.

Some versions of 'tr' only accept octal codes if entered with three digits,
and therefor misinterpret the '\0' in the test suite.

Some versions of 'tr' reject the (needless) use of character classes.
