You could try this, even though I reckon it's a rather trivial and bumpy approach. The idea behind it is to copy the file but omit the last character and thus remove the blank line.
More elegant/performant solutions might be achieved with awk, which is a science of its own

Dear All,
In a CSV file, say that a given column has been extracted. In that column, information is missing (i.e. blank lines appear). I would like to replace the blank lines by the last valid line (not blank) previously read.
For example, consider the extract below:

g3cat
g3cat(1) mgetty+sendfax manual g3cat(1)NAME
g3cat - concatenate multiple g3 documents
SYNOPSIS
g3cat [-l] [-a] g3-file1 ...
DESCRIPTION
g3cat concatenates g3 files. These can either be 'raw', that is, bitmaps packed according to the CCITT T.4 standard for one-dimensional
bitmap encoding, or 'digifax' files, created by GNU's GhostScript package with the digifax drivers. Its output is a concatenation of all
the input files, in raw G3 format, with two white lines in between.
If a - is given as input file, stdin is used.
If the input data is malformed, a warning is printed to stderr, and the output file will have a blank line at this place.
OPTIONS -l separate files with a one-pixel wide black line.
-h <blank lines>
specifies the number of blank lines g3cat should prepend to each page. Default is 0.
-L <lines>
limit lenght of output page to maximum <lines> lines.
SPECIAL-CASE OPTIONS-w <width>
specifies the desired page width in pixels per line. Default is 1728 PELs, and this is mandatory if you want to send the fax to a
standard fax machine. If one of the input files doesn't match this line width (for example because it was created by a broken G3
creator), a warning is printed, and the line width is transparently fixed.
-a byte-align the end-of-line codes (EOL) in the file. Every EOL will end at a byte boundary, that is, with a 01 byte.
-p <pad>
specifies a minimum number of bytes that each output line must be padded to. Padding is done with 0-bits before the EOL code.
-R suppress output of end-of-page code (RTC).
Example
The following example will put a header line on a given g3 page, 'page1' and put the result into 'page2':
echo '$header' | pbmtext | pbm2g3 | g3cat - page1 >page2
