Your mailer corrupted what you typed, by adding spurious newlines, and
capitalizing the if.

Your report is not a bug in bash, but in your usage.  Either quote things
properly when invoking the POSIX-specified [:

if [ 1 \> 2 ]

or use the bash builtin [[ which does the implicit quoting for you:

if [[ 1 > 2 ]]

> This should be a string compare.

Actually, when quoted properly, it should be a numeric comparison, not a
string comparison.
