[PATCH 09/10] t/t5516-fetch-push.sh: use the $( ... ) construct for command substitution

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.
