With the understanding that this depends on your shell and O/S...
'^[^\t ]' will match any line that does not being with a space, a "t" or "\".
If you want to match anything that does not being with whitepace, use '^[^[:space:]]'. If you want to limit this to a space or tab use $'^[^\t ]'.

xmtablistinserttabs
XmTabListInsertTabs(library call) XmTabListInsertTabs(library call)
NAME
XmTabListInsertTabs -- A convenience function that inserts tabs into a tab list
SYNOPSIS
#include <Xm/Xm.h>
XmTabList XmTabListInsertTabs(
XmTabList oldlist,
XmTab *tabs,
Cardinal tab_count,
int position);
DESCRIPTION
XmTabListInsertTabs creates a new tab list that includes the tabs in oldlist. This function copies specified tabs to the tab list at the
given position. The first tab_count tabs of the tabs array are added to the tab list. If oldlist is NULL, XmTabListInsertTabs creates a new
tab list containing only the tabs specified.
oldlist Specifies the tab list to add the tabs to. The function deallocates oldlist after extracting the required information.
tabs Specifies a pointer to the tabs to be added to the tab list. It is the caller's responsibility to free the tabs in tabs by using
XmTabFree.
tab_count Specifies the number of tabs in tabs.
position Specifies the position of the first new tab in the tab list. A value of 0 (zero) makes the first new tab the first tab in the tab
list, a value of 1 makes it the second tab, and so on. If position is greater than the number of tabs in oldlist, then the tabs
will be inserted at the end. If position is negative, the count will be backwards from the end. A value of -1 makes the first new
tab the last tab, and so on.
RETURN
If tabs is NULL or tab_count is 0 (zero), this function returns oldlist. Otherwise, it returns a new tab list. The function allocates
space to hold the returned tab list. The application is responsible for managing the allocated space. The application can recover the
allocated space by calling XmTabListFree.
