Fixed -N so that it cancels any keychange auth option.

More variable substitution bug fixes.

Factored variable substitution into VarSub() and fixed bug that failed to do ...

substitution on host names passed with -H.

Added variable substitution to the command passed on the command line.

Fixed bug that was causing *all* "=" signs to be removed from the RHS of a .define statement. Now it properly only uses the leftmost as a delimiter between LHS and RHS and leaves the rest, if any, alone.

Renamed tsearchpath() to SearchPath() and had it return first matching ...

filepath as a string, not a list.  Adjusted ReadFile() accordingly.
Added explicit check to make sure a FQ filename passed on the command line
was not actually the name of a directory.

Minor cosmetic change.

First full implementation of path searching for command files and host list files. ...

Implemented -x option to override -t.

Minor typo fix.

Cleaned up user name prompting and precedence.

Changed -s option to -S for consistency with -N.

Fixed sudo failure code to abort on error instead of continuing.

Added -s option and corrected sudo password prompting algorithm.

Minor change to sudo pw hint.

to login password when present.

Cleaned up sudo handling and reporting.

Cleaned up reporting output.

Modified to only trigger sudo behavior (passwords, etc.) when the ...

command string begins with "sudo " instead of just "sudo".  This
inhibits sudo behavior for commands like 'sudoedit' and 'sudoreplay' that,
if used at all, should themselves be run under 'sudo' privilege promotion.

Added ability read commands from stdin.

Changed the host separator on GETs from "-" to ":".

Bi-directional file transfer implemented.
