Summary

0002924: ash does not parse "${varname:begin:end}" for substring creation/checking

Description

The shell construct:

${varname:begin:end} does not produce the substring of $varname starting at begin and going to end.

example:

#!/bin/ash

mystr="This is a string"
echo $mystr
mysubstr=${mystr:0:4}
echo $mysubstr
#end of example

Expected output:
This is a string
This

Actual output:
This is a string
./testscript: line 5: syntax error: Bad substitution

Additional Information

This is necessary for self-hosted builds and testing.
