i stole it from handy one-liners for sed. the problem was similar to the example of a line that begins with an equal sign (sed -e :a -e '$!N;s/\n=/ /;ta' -e 'P;D')

-e cmd
Next argument is an editing command. Useful if multiple scripts or commands are specified.

:label
Label branched to by t or b.
b
Branch to label or to end of script.
t
Same as b, but branch only after substitution.

P
Print first part (up to embedded newline) of multiline pattern space created by N command. Same as p if N has not been applied to a line.

D
Delete the first part (up to embedded newline) of multi-line pattern space created by N command and resume editing with first command in script. If this command empties the pattern space, a new line of input is read, as if the d command had been executed.

of course you can also read the friendly manual

XmTabListReplacePositions(library call) 								   XmTabListReplacePositions(library call)

NAME

       XmTabListReplacePositions -- A convenience function that creates a new tab list with replacement tabs

SYNOPSIS

       #include <Xm/Xm.h>
       XmTabList XmTabListReplacePositions(
       XmTabList oldlist,
       Cardinal *position_list,
       XmTab *tabs,
       Cardinal tab_count);

DESCRIPTION

       XmTabListReplacePositions creates a new tab list that contains the contents of oldlist, but with the tabs at the positions in position_list
       replaced with copies of the corresponding tabs in tabs.	A warning message is displayed if a specified position is invalid; for example, if
       the value is a number greater than the number of tabs in the tab list.

       This  function  deallocates  the original tab list after extracting the required information. It is the caller's responsibility to free the
       tabs in tabs by using the XmTabFree function.

       oldlist	 Specifies the tab list.  The function deallocates the tab list after extracting the required information.

       position_list
		 Specifies an array of positions of the tabs to be replaced. The position of the first tab is 0 (zero), the position of the second
		 tab is 1, and so on.

       tabs	 Specifies an array of the replacement tabs.

       tab_count Specifies the number of elements in position_list and tabs.

RETURN

       If  tabs,  oldlist, or position_list is NULL, or tab_count is 0 (zero), returns oldlist. Otherwise, this function returns the new tab list.
       The function allocates space to hold the returned tab list.  The application is responsible for managing the allocated space.  The applica-
       tion can recover the allocated space by calling XmTabListFree.
