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.
