Yes to 1 and 2. All fixed:
// if it begins with a single quote then have to remove and "un-double"
any quotes
static const char quote = '\'';
if ( command[0] == quote )
{
int to = 0;
for ( unsigned int from = 1; from < strlen(command)-1; )
{
if ( command[from] == quote ) from++;
command[to++] = command[from++];
}
command[to] = '\0'; // terminate it
}

A couple of questions.
1) Will the passed parm have imbedded blanks or will it be a single string
of characters?
2) Can there be any imbedded quotes in the parm?
To fix #1, check if the first character is a quote. If so, then pass
starting from the second character and do not pass the last character (the
ending quote). So long as you pass a length, any imbedded blank should not
be an issue.
As to #2, after removing any bracketing quotes, you can either pass the
doubled single quotes or parse and rebuild the parm by converting the
doubled quotes to a single occurrence.
